Lecture 247:- HTTP Requests
HTTP (Hypertext Transfer Protocol) is a protocol used for transferring data over the internet. It is a request-response protocol, where a client sends a request to a server, and the server responds with a message containing the requested data. The HTTP requests are of different types or methods, including GET, POST, PUT, DELETE, etc.
- GET: This method is used to retrieve data from a server.
- POST: This method is used to send data to a server to create or update a resource.
- PUT: This method is used to send data to a server to replace a resource.
- DELETE: This method is used to delete a resource on the server.
- HEAD: This method is similar to GET, but it retrieves only the headers of the response, not the content.
- OPTIONS: This method is used to get information about the communication options available for a resource.
- TRACE: This method is used to get a diagnostic trace of the requests and responses exchanged between the client and server.
HTTP requests are composed of a request line, headers, and an optional message body. The request line contains the HTTP method, the URI (Uniform Resource Identifier) of the requested resource, and the version of HTTP being used. The headers provide additional information about the request, such as the type of data being sent and the format of the data. The message body contains the data being sent to the server, such as form data or JSON data.
